While concrete is the backbone of modern infrastructure, from roads to skyscrapers, producing it has a significant environmental cost. A new study by Mehdi Khanzadeh, an assistant professor of civil and environmental engineering at Temple University, explores carbonatable concrete, which could reduce environmental impact by absorbing CO2 during curing. His study introduces a new method called internal-external CO2 curing which significantly increases carbonation depth, making the material stronger and more durable. Initial tests show that concrete made this way has an 80%–100% improvement in mechanical and durability performance compared to current carbonatable concrete. The research is still in its proof-of-concept stage. If successful, this innovation could help shift the construction industry toward more sustainable practices.
